San Marcos sits at the midpoint between San Antonio and Austin on the I-35 corridor, where steady growth has produced a housing stock that spans everything from older historic neighborhoods to recently built subdivisions. The city’s position between two major metro areas means it shares the summer heat patterns of both, and the Blanco River corridor adds humidity that puts extra demand on cooling systems. Jon Wayne serves San Marcos with full HVAC, plumbing, and electrical coverage.

Our 100% satisfaction guarantee covers equipment, service, and workmanship, and upfront flat-rate pricing means no surprises on your invoice. For emergencies, Jon Wayne is available 24 hours a day.

Frequently Asked Questions

Older San Marcos properties, particularly those that have been rental housing for years, often have deferred maintenance on electrical panels, plumbing, and HVAC systems. Systems that have been running without professional service can accumulate issues that aren’t obvious until they fail. If you’ve recently purchased an older San Marcos home or are a homeowner transitioning a property from rental use, a professional review of all three major systems is a worthwhile starting point. Jon Wayne can assess HVAC, plumbing, and electrical and give you a clear picture of what needs attention.
Yes. San Marcos draws from the Edwards Aquifer, which produces water with high mineral content throughout the region. Scale buildup in water heaters, pipes, and fixtures is a consistent issue. The San Marcos River area also adds ambient moisture that can affect the humidity load on AC systems. Jon Wayne installs whole-home water softeners and can assess your water heater’s current condition during a plumbing service call.
San Marcos sits in a zone where hard freeze events, while not annual, do occur with enough regularity to warrant preparation. The 2021 winter storm caused significant plumbing damage throughout the I-35 corridor, and homes that weren’t prepared suffered burst pipes and extensive water damage. Pipes in exterior walls, garages, and unconditioned attic spaces are most vulnerable. Jon Wayne’s plumbing team can assess your home’s freeze vulnerability and recommend insulation or shutoff valve work that reduces risk.
In older San Marcos properties, panel upgrades are the most common request, original panels from the 1960s through 80s frequently don’t have the capacity for today’s loads. GFCI protection in older bathrooms and kitchens is another common upgrade. In newer construction around the growing parts of San Marcos, whole-home surge protection and smart home installations are increasingly common. Jon Wayne’s licensed electricians handle all of those with upfront pricing on every job.
March or early April for the AC, and October for the heating system. San Marcos sees both hot summers and genuine winter cold fronts, which means both systems need to be ready for their respective seasons. Jon Wayne’s 5-Star Service Club covers both seasonal tune-ups at $29.99 per month and gives members priority scheduling so they’re ahead of the rush before each season begins.
